■ b5-40: Frequency Reference Monitor @PID
No.
(Hex.)
Name Description
Default
(Range)
b5-40
(017F)
Frequency Reference
Monitor @PID
Sets the contents for monitor U1-01 [Frequency Reference] in PID control.
0
(0, 1)
0 : U1-01 Includes PID Output
Monitor U1-01 shows the frequency reference that was increased or decreased by the PID output.
1 : U1-01 Excludes PID Output
Monitor U1-01 shows the actual frequency reference.
■ b5-47: PID Trim Mode Output Reverse Sel
No.
(Hex.)
Name Description
Default
(Range)
b5-47
(017D)
PID Trim Mode Output
Reverse Sel
Sets reverse motor rotation when the PID control output is negative.
1
(0, 1)
This parameter is enabled when b5-01 = 3 or 4 [PID Mode Setting = Fref + PID Trim, Fref + PID Trim (D on
feedback)].
0 : Lower Limit is Zero
When PID output is negative, PID output is limited to 0 and drive output is shut off.
1 : Negative Output Accepted
When the PID output is negative, the motor will rotate in reverse.
■ b5-53: PID Integrator Ramp Limit
No.
(Hex.)
Name Description
Default
(Range)
b5-53
(0B8F)
RUN
PID Integrator Ramp Limit
Sets the responsiveness of PID control when the PID feedback changes quickly.
0.0 Hz
(0.0 - 10.0 Hz)
Note:
• This parameter is disabled when set to 0.0 Hz.
• When b5-53 > 0.0 Hz and the drive enables the integrator ramp limit, the PID integrator value limit is the range set by the output frequency
± b5-53.
• When the PID feedback changes quickly, gradually decrease the this parameter in 0.1 Hz increments to decrease the speed of the response
of PID control.
■ b5-55: PID Feedback Monitor Selection
No.
(Hex.)
Name Description
Default
(Range)
b5-55
(0BE1)
PID Feedback Monitor
Selection
Sets the monitor (Ux-xx) used as the PID Feedback. Set the x-xx part of the Ux-xx [Monitor].
